EXTENSION EAB IQE Specification of Letters Patent.

Patented Nov. 10, 1908.

Application filed April 7, mos. Serial No. 425,595.

To all whom it may concern:

Be it known that I, ANDREW H. STONE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Extension-Ta,- bles, of which the following isa specification.

This invention relates to circular extension tables and is designed more especially as an improvement on the extension table on which I filed application Dec. 24, 1907, Ser. No. 407,940, and my object is to produce a table of this character of as strong and durable but simpler and cheaper construction than that on-whieh said application was based. y

To this end the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in orderthat it may be fully understood reference is to be had to the accompanying drawing, in which- Figure 1, is an inverted plan view of a portion of a table cmbodyin my invention. Fig. 2, is a vertical section 0 the table taken on the dotted line II of Fi 1. Fig. 3, is a section taken on the line I I-III of Fig. 1. Fig. 4 is a section on the line IV-IV of Fig- 1.

In the said drawings, 1 indicates the support or pedestal of the table surmounted by a cross bar 2, upon which the circular table top 3 is secured and secured to the underside of said top at opposite sides of the cross bar is a pair of blocks t. 5 are brackets secured to the underside of cross bar 2 and blocks 4, )rovidcd at their outer ends with lugs (3 an in their body "portions with longi-' tudinal slots 7 through which guide screws 8 aextend up into the cross bar and the blocks, to facilitate the proper adjustment of the brackets, additional screws likewise being employed to secure said brackets rigidly in position after their proper adjustment has been effected as shown in Fig. 1.

9 indicates a circular rim of smaller diameter than the table to and arranged under said top concentrica ly around the support-or pedestal outwar of said brackets and secured to the inner side of said mm are horizontally arranged segmental brack-' ets 10, U-shape in plan view provided. with cam or inclined slots 11, the vertical distance between the ends of such slots determining the amonnt. ofvertical movement of the rim, said brackets 10 are provided with vertical slots 12 through which. ide screws 13 extend into the mm, the s ots of said brackets bein engaged by the lugs 6 of the adjacent brac tots, and after the proper adjustment between the two sets of brackets 'is eifected additional screws 14 are employed to secure brackets 10 rigidly'in position.

To vertically adjust the rim with respect to the top, said parts are grasped and ressure isapplied thereon in ,opposite irections, this action accordingly as pressure is applied in one direction or the other causing the rim to rotate and at the same time movesm upwardly or downwardly. a

To increase thesize of the table, I provide a plurality of segment-shaped sections 15. adapted to fit against the outer edge of the top, said extension sections having'their radial edges stepped seas to fit together as shown at 16, Fig. 4. 'Pivoted to each extension at 17 is a pair of bars 18, 'said bars being preferably pivoted to the extensions at different distances from the center of the table so that said bars, when the extensions are not in use may be folded to the osition indicated on the lower extension in ig. 1.

19 indicates clips 0 en at one end and secured to the under si e of the extensions to receive the outer ends of bars 18 preliminary to securing the extensions in operative position, said clips holding the bars when thus operatively arranged in substantially paralle relation and projecting beyond t e inner edges of the extensions.- The extensions are secured in position by slipping the bars 18 inwardly between the top and therim when the latter is lowered until the inner ends of the bars project through the kee )ers 20, secured to the underside of the table top, the parts being then secured in this position by turning the rim and causing it to move upward until it clamps tightly upon bars 18.

To brace the extensions at their stepped edges, from springing or moving in a vertical direction, turn buttons-21 are secured to their undersides, in such sition that when turned properly, they she I underlie the end of the adjacent section as shown clearly in Figs. 1 and 4.

Io remove the sections, the rim is first turned in the proper directionto lower it and relieve bars 18 of the pressure. The turn buttons are then swung around from under the contiguous sections, when all of the sections may be drawn outwardly and then removed from the table. The rim is then preferably turned so as to raise it until it engages the lower side of the top.

From the above description it will be apparent that I have roduced an extension table possessin the eatures of advantage enumerated and I wish it to be understood that I reserve the right to make all changes falling within the spiritand scope of the sections and interposed between the top and the rim elements and extending through the keepers secured to said top element.

2.'In an extension table, a top element and a rim element relatively movable vertically, a support rigid with oneof saidelements, keepers secured to the'underside of the top element, se entsshaped extension sections fitting against the edge of the top element and endwise against each other, and bars pivoted to the underside-of said sections, and interposed between the top and the rim elements and extending through the keepers secured to said top element.

3.'In an extension table, a top element and a rim element relatively movable vertically, a support rigid with one of said elements, keepers secured to the underside of the top element, segment-shaped extension sections fitting against the edge of the top element and endwise a ainst each other, bars pivoted to the undersi e of said sections and interposed between the top and the rim elements and extending through the keepers secured to said top element, and clips secured to the underside of the sections and enga ed by the outer ends of saidpivoted bars when the latter are in engagement with said keepers. i

4. In an extension table, a top element and a rim element relatively movable vertically, a support rigid with one of said ele ments, keepers secured to the underside of p the top element, segment-shaped extension sections fitting against the edge of the top element and endwise a ainst each other. oars pivoted to the undersi e of said scctiorand interposed-between the top and the rim elements and extending through the Rec ers secured to said top element, and turn uttons secured to said sectionsjpnd ada ted to underlie the adjaceit sections when t e pivoted bars are in engagement with the keepers.

In testimony where--f I aflix my signature, in the presence of two witnesses.
